Still unsure what is going on though, other than after 2-3 hours of cd player the engine wouldn't start... then 10 mins of charge she springs in to life???
Obviously the cd, vhf and GPS must be taking power from the starter battery and then the domestics from the the leisure batteries... Which in my view is a bit daft... I couldn't get a good view of what was connected behind the panel, but I would like to find a way of moving everything to the leisure batteries, that way I know I can get started and once i'm started the other batteries will be charging anyway....
There is a 12v fuse panel in the cabin perhaps I can find what is feeding that and move things around?
anyone confident to do this and wants to earn a beer token or 2?
